Airslide sampler HR-RN

The solution for sampling of powder material from horizontal conveying processes

Area of application

Sampling of powder material from horizontal air conveyor troughs

Powder (cement and other, feed size max. < 200 µm)

Operation mode
Automatic, manual


Proven technology
The HR-RN air slide sampler is designed for the sampling of powder and fine-grain materials from horizontal air conveyor troughs. The HR-RN is a well-proven sampler which is used in many cement plants and other production facilities.

Reliable sampling
A perforated collecting tube located vertically in the air conveyor trough retrieves the sample from the material flow. The perforations in the collecting tube are rotated into the material flow for the purpose of sampling. In the closed condition, the holes are turned in the opposite direction. The collecting tube is driven pneumatically. Once retrieved, the sample can be transported through a downcomer directly into a downstream process station. The sampling cycle is controlled by the controller of the process station.
